GAUGING DEVICE.

Application filed April 14, 1921. Serial No. 461,23.

To all whom it may concern:

Be it known that 1, JOHN C. BACKERT, a citizen of the United States,residing at Lynbrook, in the county of Nassau and State of K New York,have invented certain new and useful Improvements in Gauging Devices, ofwhich the following is a specification.

My invention pertains to gauging devices for use in cutting the ends oftype slugs, brass 1 rule or the like to a bevel.

In the patent granted July 26, 1921, to William M. Garwood, and numbered1,385,- 782, for bevelling devices, there is described a device for usein bevelling type slugs, brass rule or the like, by means of which theslugs, or the like, to be bevelled may be made to project beyond theline of cut of the cutter just a sufiicient distance to permit thecorners to be removed without interiering with the length of the slug,the device including means for thus spacing the corners of the slugsbeyond the line of cut. The object of my invention is generally toimprove upon devices of this character, and to provide such a devicewhich can be especially quickly-and easily operated, which will be of asimple and strong construction, and which can be attached-to preexistingslug-cutting machines. Other special objects of my invention will appearfrom the following description, taken in connection with the claimsannexed thereto.

By way of example, I have described one lib form of device in which myinvention may be embodied in the following specification,

and shown such embodiment in the accompanying drawings, in which:

Fig. 1 is a plan oi a cutting machine for type slugs and the like,having applied thereto a gauging device constructed in accordance withmy invention, the gauging device and the end gaugeoi the cutting machinebeing shown in the position which they occupy when the gauging device isbeing set to position for bevelling slugs two points in thickness;

Fig. 2 is a artial plan, of a diagrammatic nature, s owina the manner ofusing the gauging device for positioning the slugs priorto the bevellingcut;

Fig. v3 is a plan of the gauging device; Fig. 4 is a partial planshowing the bevelling device with the index head and index fingerremoved, to disclose the spacing meme her and the cam for operating thesame; and

Fig. 5 is a longitudinal section, taken on the line 55 of Fig. 3,looking in. the direction of the arrows.

The gauging device of my invention is well adapted for use inconnectionwith a slugcutting machine such as is described in Harry G. MillerPatent No. 986, i85, granted March 14:, 1911, for Vises. Such aslug-cutting machine comprises a support carrying a fixed table 10 and amovable table 11, the latter being capable of being slid'to and fro toenable thework thereon to be operated on by a rotary saw 12 Mounted uponthe sliding table 11 is a rest consisting of a side gauge 13, which isgraduated pioas, and an end gauge 14 extending at right angles to theside gauge and slidable thereon, said end gauge carrying an adjustingworm 15, graduated to points engaging corresponding worm grooves in theside gauge 13,. The side gauge 13 is normally positioned at right anglesto the cutting plane of the'saw 19f, but it may be swung so as to assumevarious other angles with such plane, the most frequently used angle,after the right angle, being that at which the side gauge extends atdegrees from the line of the out oithe saw. To permit this swinging, theside gauge 13 has extending therethrough a follwer pin 13 having anarc-shaped extension rigid relative to the side gauge and adapted toextend into an arcshaped groove 13 formed in the. table 11, this groovebeing so arranged that when the side gauge is swung around, it will bemoved in the arc of a circle having its center on the line of out of thesaw 12*. A1001:- ing pin 13, inserted through the side gauge, fits inopenings on the sliding table to lock the side gauge in the position towhich it may be moved. A. vise co-operates with the side gauge andincludes a vise bar 16, operated by handle 17. The end of the side gaugeis squared so as to provide a surface 18 at right angles to the mainslug-engaging surface 1.9 of the side gauge, againstwhioh surface 18 theslugs may be held when being bevelled for the second time, therebyobviating the necessity of turning them over and cutting them with theprinting faces downward. On the fixed table 10 is mounted an abutmentmember 20 havinca slug engaging face 21 parallel the cutting plane ofthe saw, and having a shank 22 extending at right angles to said plane,the bottom of said shank being formed with a tongue 23 which slidablyengages a groove 24 formed in the top of the fixed table 10, whereby themember 20 may be slid forward and backward with its face 21 maintainedparallel with the cutting plane. A cap screw 25, passing through a slot26 extending lengthwise of the shank 22, and entering one or the otherof two holes in the fixed table 10, serves to hold the member 20 in anyposition to which it may be adjusted. The machine, as thus fardescribed, is old and well known in the art.

If a plurality of slugs, previously cut to a predetermined length withtheir ends square, be placed as indicated in Fig. 2, engaging againstthe side gauge 13 swung into a 45 degree position, with their rearcorners located on the line of the cut of.

the saw, and if a out be then made, it is obvious that the corners 0 ofthe slugs which project beyond the line of cut dc will be removed, andthat the slugs b will thus be mitered without the predetermined lengthsof them being changed. By placing the member 2O so that its face 21 isthe proper distance from the line of cut d--e, it merely becomesnecessary, in order to place theslugs b properly for the mitering out,to hold them against the face 19 of the side gauge 13 and shift themuntil their front corners engage the face 21 of the member 20*. With theslugs thus placed, and secured in position by the Vise bar 16preparatory to the out, they will be accurately mitered with out anychange length. It will be noted that the position of. the face 21 of themember 20 with respect to the line of cut d-e will vary in accordancewith the thickness of the slugs to be cut. I

To provide for the placing of the memher 20 so that its face 21 will bein the proper position, with respect to the line of cut de, for theparticular thickness of slug being mitered, I provide. the. member 20with a plate 28, in Which slides, a spec ing member 29, such spacingmember being adapted to extend'beyond the face 21 for a distance whichcan be made to accord with the thickness of the slugs to be mitered.l'f'the end gauge 14 be set to zero-i. e., to the position in which itsface is located on the line of the cut of the saw (Fig. 1)- and-themember 20 be then slid up until the projecting spacing member 29 engagesagainst said end gauge 14, then, if the spacmg member has been adjustedto project the correct distance for the particular thickness of'slugs tobe mitered, the face 21 of the member 20?* will be in the correctposition for spacing the corners of such slugs, in the manner abovereferred to, and indicated in Flga I 2.

nears-ea To provide for the required adjustment of the spacing member29, l mount eccentric 30 in the plate 28, so as to be capable of beingrotated on a stem 31 which enters said plate and is secured therein by anut The reduced end 29"- of the spacing member 29 engages against theeccentric 30, and is held in such engagement by a spring 33, located ina recess 34 of the spacing member, which spring engages against a pin 85extending upward from the member 20 at the part where the spacing member29 projects therethrough. It is obvious that the turning of theeccentric 30 will effect an adjustment of the spacing member 29, cansing it to project to a greater or less ex tent beyond the face 21. A.lmurled knob 36 is provided, by means of which the eccentric 30 may beturned, and beneath this knob 36, to cover the depression 37 of theplate 28 wherein the eccentric 30 lies, there is provided an index plate38. The plate 38 is marked with a number of index lines denoting variouscommon thicknesses of slug, one or another of which index lines comeopposite a pointer 39, carried by the member 20 when the eccentric isturned by means of the knob 36. The index lines on the plate 38 aremarked with numbers corresponding with the various thicknesses of slug.Thus, when the eccentric has been turned until the index line marked 2is opposite the pointer 39, the eccentric will be in such position thatthe spacing member 29 projects the correct distance to position themember 20 so that its face 21 is properly placed for mitering two-pointslugs.

In the use of my improved device-for instance, to miter four two-pointslugs to make a square border,the four slugs are first cut at. each endto the predetermined length of he side of the square, the side gaugebeing in the right-angle position shown in Fig. 1; the end gauge is thenmoved. down to the zero position, and the member 20 is moved laterallyuntil the spacing member 29, previously set for twopoint slug, engagesthe said end gauge, 14; the member 20 being thereafter locked by meansof the cap screw 25; the end gauge 14 having been moved out of the way.and the side gauge 13 having been swung to the 45 degree position asshown in F ig. 2, the slugs are placed against the face,19 of the sidegauge with their corners abutting against the face 21 of the member 20,being secured in such position by the vise and the first mitering cutmade; and the slugs are lastly made to engage against the face 18" atthe end of the side gauge, with the corners of their uncut ends abuttingagainst the face 21 of the member 20 and the second mitering cut made.In this way, a border may be very easily and quickly made to any desireddimensions. Other very important uses of the device will be apparent tothose skilled in this art.

An advantage of the device lies in the ease and speed with which therequisite adjustments may be made, as Well as in the strength andsimplicity of the construction. A further advantage of the device isthat it may be readily applied to pits-existing machines, without thenecessity of any modifications thereof, or of any mechanical workthereon.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:
